Abstract

This study examined the validity and reliability of a computer graphics (CG) version of the controllability of motor imagery (CMI) test of Nishida et al. (1986). The CG version of the CMI test was developed using Poser6. The test was administered to 324 male and female undergraduates. The correlation between the original CMI test and the CG version was r=0.456. In addition, the test scores did not differ significantly between athletes and non-athletes, although athletes should have a better ability to control motor imagery than non-athletes. Concerning reliability, Cronbach's alpha was 0.715, and the correlation using the test-retest method was r=0.403. These results imply that the CG version of the CMI test lacks suitable validity and reliability. We postulate that this is because the CG is projected on a screen when answering the test. Therefore, it is necessary to administer the test individually.
